摘要：

In this paper we calculate the next-to-leading-order (NLO) corrections to rho-meson electromagnetic form factors by employing the k(T) factorization approach. We find that the NLO correction to F-i (Q(2)) (i = LT, TL) is around 30% of the leading-order (LO) contribution in the region Q(2) > 2 GeV2. The NLO correction to F-LL (Q(2)) is close to 20% of the LO one in the region Q(2) > 3 GeV2. The NLO radiative corrections to the electric, magnetic, and quadruple form factors F-j (Q(2)) (j = 1, 2, 3) are sizeable in magnitude and agree with those from other approaches.
